' sncrronan ExPANDILNG DRUM.

To all whom it may concern: Y

' A Be it known that ]-,.S.\MuiinV L. HiRscHEY, a citizen ofthe United States, residing at Castorland, in the county of Lewis and State of New York, have inventedcertain new and useful Improvementsin Sectional. ExpandingDrums; and I do hereby Ideclare the following to be a full, clear, and exact description of the invention, such .as will enable others skilled in theart to which Vit appertains to make and use the same, referencebeing-had to the accompanying drawings, and to the letters and iigures of reference marked thereon, which forma part of this specification.

This invention relates to new and usefulv improvements in drums for usein making cylindrical ber boxes and comprises essentially an. expanding cylinder madeup of a series of rods spaced apart and secured to the heads of the drum of the cylinder, the drum being made of sections and adapted :to be expanded by a cam upon-a rock shaft.

' The invention comprises a simple and eilicientV apparatus of this naturehaving various details of construction, combinations andy `arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically deined in the appended claims. n

My invention is illustrated in the accompanying drawings, in which: yi

Figure lis an end view of an expanding cylinder made in accordance with my invention. Fig. 2' is a vertical longitudinal sectional view through the drum. Fig. 3 isaJ crosssectional view. Fig.y 4 is a sectional view taken on line 4 4 of Fig. l. l

Reference now being had to the details of the drawings by letter,fA and B designate two semi-cylindrical sections of the drum, which together make up a cylinder, the circumference of which is composed of rods C, spaced apart slight distances. In the drawings the ends of the sections, which are shown'as solid, are provided with bearing recesses D atv their meeting edges, and F designates lateral projections upon the ends of the section A, each projection having a bearing aperture G for the shaft which rotates the drum. Guide projections, designated by letter H, extend beyond the inner straight edges of the ends of the section B and are adapted to have sliding contact with the opposite edges of the project Specification of Letters Patent.

ing portions upon the ends yof the sections A, serving to guide the two sections as they are moved away or toward each other in a manner which will presently bedescribed.

K is a cam shaft which is journaled in apertures in the projections Fand the cam shaft is provided with circumferential slots I, the bottoms of which slots are so shaped as to form cams and the ends of thesection Bv `formed laterally recessed as at O to receive a plate Q which may be readily removed should it be desired to remove the shaft K for any purpose.

A. crank L has a hollow hub portion which is mounted upon the shaft K and said shaft has a hollow end, the wall of which is interiorly threaded as at T which threads are engaged by the threads of the screw S, the inner end of the latter being tapered as at S. The wall of the hollow portion of the shaft has a hole leading from the interior vthereof through its circumference anda pin W is mounted in saidhole and has its inner end tapering and is disposed in the path of the inclined tapering end of Vsaid screw. Said screw is adapted, when turned in one direction, to contact with the tapering end of the pin W and cause the outer end of the latter to frictionally engage the inner circumference of the hub of the crank L and serve as a means for securely locking the same upon the shaft K. Said crank, it will be noted, has a series of markings M thereon, forming indicating means whereby the crank may be held in diiferent positions upon the shaft for the purpose of expanding the drum to different diameters as may be desired. A hollow handle X is fastened to said crank and carries'a spring-pressed pin adapted to engage a recess in the end of one of the sections to hold'the crank in adjust-v ed position, the'pin, which is spring-actu-V ated. being easily retracted within the handle by pressure thereon when it is desired to move the crank. Pins, designated Aby let-ter J, project fromone end ofthe section B and arerspaced apart,vadaptedto Y. form stops to limit the rocking movement of Vmak-ing body portions of fiber Vboxes is as follows One end of the sheet of paper'or fiberfroin which the box is to be made is placed against the circumference of the drumwith its edge underneath the fingers Mf The operator then, by swinging the crank and giving the shaft K a partial rotaryi movement, may cause .they two sections i of the drum to expand,which movement. is

dueto the cams upon theshaft K coming in vcontact with theY edges of the bearings as shown and which movement will cause the end of the paper to be securely clampedn and, 'after which, a rotary movement. is imparted to the cylinderl to cause the sheet of paper to windabout the drum as many plies as may be desired, suitable adhesiveV material being applied to cause'the folds of the paper to adhere to each other. After the proper thickness of the body portion of the box has 'Y been formed, the rotary movement of the drum is :stopped and the operator, by imparting a yreverse rocking movement to the shaft K, may cause the two sections of the druinto. Contact or returnl'to their normal positions, thus allowing the body portion of the 'box that has'been forniedvfto be readily Y removed from the cylinder or drum.

What I claim to be new is 1 An expandingdrurn for making cylin-Y drical fiber boxes, made up of expanding sections,the circumferences of said sections upon one of said sections coperatingjwith one of said rodsr on the other section to clamp being made up lof rods 'spaced apart', means and hold'the sheet of fiber-to the cylindrical section,fwhile the sheet winds about the drum as the latter is rotated.l Y 9 2. A sectional expanding drum, the cir-v cumferences of ywhich are formed of rods spaced apart, one of saidv sections having projections thereon which are `apertured, a shaft journaled in said apertureS, YSaid shaft having a cani thereon adapted'to engage'the other section to cause the two sections to ex- Y pand as the shaft is rocked, and clamping means upon said projections coperating f with a rod upon an adjacent section toV hold theend of a sheet of*v paper while being wound about the drum.Y
